YARN-SPECIE( REMOVER.

Specification of Letters Patent. Patented lynn', 23, 1920,

Application filed November gli, 1919. Serial No. 340,211.

17h all wwm 'it may concern Be it known that I, WILLIAM F. MOON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of ViscOnsin, have invented new and useful Improvements in Yarn-Speck lvlemovers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The present invention relates to a device for removing lumps of fiber or what are commonly termed specks from yarn or thread, previous to its use in a spinning or weaving machine.

@ne object of this invention is to provide a device of this character which will include rotating members for crushing or severing the speck from the threat Jlnother object of the present invention is to provide a device of this character which will have revoluble and yieldable means cooperating with a speck positioning member to crush or sever the speck from the thread or yarn.

A, further object of this invention is to provide a device of this character having a revoluble speck positioning member, and a revoluble crushing Wheel yieldingly held in engagement therewith whereby friction is reduced to a minimum.

With the above and other objects in view which will appear as the description pro ceeds, my invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

ln the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof. and in which:

Figure l is a side view of a yarn speckremover embodying` the principles of my ini vention, said view having parts broken away and in section to more clearly illustrate details of construction.

F ig. 2 is a view, part in section and part in elevation, said view being taken on the line it- 2 of Fig. l.

Llig. 3 is a side view of a slightly modified form of my invention, said view having parts broken away and in section, and

Fig. 4 is a view, part in section and part in elevation, said view being taken on the line 41-41s of Fig. 3.

Referring now to the drawings, and more particularly to Figs. l and 2, the numeral 5 designates generally the frame of my machine which has a plurality of pairs of opposed upwardly extending arms 6 rigid with the frame.`

ln the drawing, I have illustrated a plurality of speck removing devices carried by the frame 5, each of which successively acts upon the thread or yarn to remove any specks thereon, so that if the first device does not remove the speck it will be removed by another of the devices.

Each of these speck removing devices is disposed between the adjacent pair of arms 6, and consist generally in inea-ns for presenting the speck in a position in which it may be readily severed from the thread or yarn by means cooperating with the speck positioning means, as hereinafter described.

The means for presenting the speck in position to either side consists of a revoluble bed block i' rotatably mounted in the frame 5 intermediate each opposed pair of arms 6 by means of journals 8 and 9, as best shown in llFig. 2. The bed block 7 in the shape of a roll and coacts with the crushing or severing means, to be later described, to remove the specks from the yarn or threadl() as it is guided through the frame. The yarn or thread 10 is guided through the frame 5 by suitable guiding members 1l and l2, located at each end of the frame,

and the thread in its passage through the frame engages the top of the bed block, and should the speck be on the under side of the yarn or thread, the same will be turned or positioned to one side, there to be severed or crushed from the yarn or thread by the coperating means, as will be later described.

As the bed block 7 is insufficient in itself to properly retain the thread upon its top surface, in that the 4thread would possibly become disengaged therefrom, I so construct `my severing or crushing means as to be con stantly in yielding engagement with the `bed block to provide what may be termed a guide channel for the thread or yarn as it passes over each bed block. The severing Dr crushing means consist of a pair of rev oluble crushing or cutting wheels 13 carried bythe adjacent pairof arms 6 andhaving their crushing or severing edges at .all

times yieldingly held in engagement with 5 the adjacent bed block 7.

The upper lend lof each larm 6 is formed with a' cylinder orcentrally aperturedA cap 14, in which is slidably, mounted a hollow sleeve end of a retaining block 16.

i0 Mounted within-the hollow of the sleeve 15 is an extensible spring 17 having its upper end bearing against a plate 18 disposed Within the vaperture of the cap 14 and ear- `ried by a tension adjusting screw 19. One

Y 15 crushing or cutting wheel 13 is rotatably secured to the inner face of each retaining block 16'by means of a journal 2O and has its crushing or severing edge Ayieldingly heldj in engagement with the adjacent bed 20 block 7 by means of the spring 17.

Arlhe wheels 13 of each pair are spaced Aapart a4 distance substantially equal to the thickness of they thread or yarn being cleaned as it is guided through the frame,

2.5 between the'wheels ofeacli pair, by the guidon the underside of the thread or yarn, will be positioned to Lone sideand severed or crushed from the thread or yarn by the co- 3,0v operating bed block. 7 and the wheels 13, which rare rotated by the means now about to be described'. .j f

rFhe journals 9 of the bed blocks are projected-'outwardly of the frame 5 and have worm gears 21 secured thereto, which worm gears are in mes'hf with worms 22 formed on a drive shaft' 23 journaled in the adjacent side' of the'frame. The shaft 23 is rotated by any desired means and'in the present in- 40 stanceV I have illustrated the same as connectedwith a pulley 24, Vconnected with a suitable source of power (not shown), by a gear pinion 25 fixed to the shaft 23 and in mesh with av gear ypinion V26 fixed to the shaft 27 of the'l pulley 24. A Y

The bed block 7 'fot each speck removing device is thus rotated inthe direction off arrow '28, see Fig. 1', and the'c'rusliing or cuttingwheels 13 a're'alsol rotated in thefdirection of arrow 29 by reason of their engagement' with the adjacent bed block. With this' structure', the speck as it is positioned to Vthe side is engaged between the bed blocks and the crushing or cutting wheels and removed from the thread or yarn up clo'setheretol 'by reason of the wheels 13 of eachpairbeing'spaced aparta distance only Y equal tothe thickness of the thread. In this manner 'the thread or yarn is thoroughly e0 cleaned andif a speckisfskipped-'by one device it'is rem'ovedfby another;

Inthatform'? of'my invention depicted in Figsj3` and 47 the armsare each' formed at their" upper ends with a bearing portion 30 projecting inwardly over the' adjacent ing members 11 and .12, and the speck, il?V bed block 7. In this instance the bed blocks A are j ournaled in a sliding block or retainer 31 mountedV in the frame 5 and normally yieldingly urged upwardly by means of a tension spring 32, and the crushing or cutting wheels 13 are splined to the portion of the shafts 33 disposed between the adjacent bearings 30 by a key member 34.

The wheels 13 of each pair are held in spaced relationby means of a spacing collar 35 and have their crushing or severing edges at all times in engagement with the adjacent bed block 7, as in that form of my invention depicted in Figs. 1 and 2. The yielding engagement between the wheels 13 30 and bed blocks 7 is adjustable by means of the adjusting screws 3G, see Fig. 4.

In this form of my invention the wheels 13 are positively rotated by the shaft 23, the worms 22 of which mesh with worm g5 gears 37 fixed to one end of shafts 33, and the bed blocks 7 are rotated by reason of their rictional engagement with the wheels 13. The direction ofrotation of the wheels 13 and bed block 7 is as indicated by arrows ce 38 and 39 respectively, see Fig. 3, and as the operation of this form of my invention is identical with that iorin of my invention depicted in Figs. 1 and 2, further descrip tion is thought unnecessary.

From the foregoing description, taken in connection with the accompanying drawing, it will be at once apparent that I provide means ,for positively cleaning or removing specks from thread or yarn prior to its use in a spinning or weaving machine.
